I'd guess that in the hour or so I spent there, a couple of hundred people cycled through the restaurant. That'd include those who were there when I arrived (it was full) and those who came through while I ate (it was still full when I left). And this was nothing special, just an average Monday Lunch crowd.
Kind of puts the "850" number into perspective, I think.
It sure does, especially now that we know the 850 make up only 3 % of the student body pop. - about the same % that the gays make of the human pop.
